> their need to signal the world how special they are and how important their interests are
Honestly, the compulsion to accuse others of narcissism for something as harmless as putting stickers on their personal property screams "LOOK AT ME, I'M SPECIAL" much more.
I was accusing others for being insincere, not narcissistic. Guess you've read only the quoted part of my message, hope the reason is not some sticker on the inside blocking the view.
I have nothing against being narcissistic, provided you are honest about it. If I say that you are trying too hard with your "No u!" game, will you accuse me of trying too hard?
